Clearing the Air with Crankcase VentilationDue to the growing importance of safeguarding our global environment, efficient crankcase ventilation filtration systems are increasingly critical to diesel engine Original Equipment Manufacturers (OEMs) . Future worldwide diesel engine emission regulations will require OEMs to continue to reduce total particulate emissions . Current emission regulations in some regions and market segments cover total engine emissions, which include both tailpipe and crankcase . Since crankcase emissions can contribute up to 25% of total emissions, control of this air pollution source is critical to the protection of the earth’s environment .
Blow-by: An Increasingly Significant Environmental ImpactA significant contributor to environmental degradation is engine crankcase blow-by . During diesel engine operation, blow-by is generated by the leakage of combustion gases past piston rings . The blow-by is typically laden with oil droplets which can be divided into two classes based on particle size:
1 . Drip (visible drips or puddles of oil)
2 . Aerosol (sub-micron oil drops that create the oily “smoke” seen at the crankcase vent)
During engine operation, the concentrations of oil droplets between 3 and 20 μm tends to be low . As a percentage of total mass, most of the oil is present either as large drips or as aerosol particles smaller than 3 μm . The major challenge for crankcase ventilation filtration is the removal of aerosol particles . A considerable portion of aerosol particles are in the 0 .2 to 0 .3 μm size range, the size of maximum penetration or are in the size range of 0 .2 to 3 .0 um . This size range creates a significant challenge for all but the most advanced crankcase ventilation filtration products such as the coalescing technology provided by Cummins Filtration® .
Without adequate and effective filtration, significant amounts of aerosol may be present in blow-by . Crankcase gases must be particularly well cleaned in order to minimize turbocharger and intercooler deposits and fouling, as well as to reduce particulate loading on the exhaust aftertreatment system .
There are two basic ways of venting crankcase emissions, either into the atmosphere – Open Crankcase Ventilation (OCV) – or routing the crankcase gases back into the engine air intake system – Closed Crankcase Ventilation (CCV) . Cummins Filtration offers both OCV and CCV approaches to manage crankcase blow-by on diesel engines .
Leading the Way with the Right TechnologiesCummins Filtration has emerged with twelve US patents on or related to CV filtration, plus some related ancillary patents . Our CV patents cover coalescers, impactors and Electrostatic Droplet Collector (EDC) devices . The company also holds a patent on a rotating coalescer design and eight patents based on coalescer technology, alone or in combination with an impactor . A number of patent applications covering other CV technologies are awaiting approval .
Depending on customer requirements, our CV products may be used alone, with performance enhancing features, or in combination with other technologies to achieve desired levels of performance . Today, they are used on nearly every major make of on-highway and industrial diesel and natural gas engine in North America and Europe .
Cummins Filtration Crankcase Ventilation systems are innovative products which are specifically designed to provide the type of performance the marketplace and the environment requires .
Product features include:
• Superior aerosol filtration, 98+% efficiency
• No service required for the impactor
• Easy service access
• Easy installation
• Durability
• Integrated electronic sensor
• Easy and versatile engine and/or equipment integration
• Easy access to service the coalescing filter elements
Introduction

Product benefits include:
• Reduced engine oil consumption
• Reduced engine maintenance due to residual oil drip build-up
• Increased uptime
• Quick and easy service
• Reduced environmental impact and waste
• Flexibility as most of our products can be applied in either OCV or CCV mode
Optional features include:
• Crankcase ventilation heat for cold ambient conditions
• Heater options for cold ambient conditions (on select products)
• Oil drain check valves
• Crankcase Depression Regulation (CDR) valves
• Filter Minder® visual restriction gauge
• Crankcase pressure sensor
Fleetguard® crankcase ventilation systems are capable of vastly reducing the amount of contaminates either vented to the atmosphere or circulated back into the air intake for a wide variety of today’s diesel engines, keeping the turbocharger and heat exchangers clean and performing well . To maintain a vehicle’s optimal performance, and in order to operate under warranty, it is important that installation recommendations be met . If there are any questions, a Technical Assistance Specialist should be called . A list of the worldwide Customer Assistance Centers may be found on the back of this document .
